What I did: Accessed the main site as
https://mindcontrolcomics.com/home instead of
http://mindcontrolcomics.com/home (HTTPS instead of HTTP)
What I expected to happen: The page to work as normal.
What actually happened: The page content loaded, but the site's web design didn't, because the links in the HEAD element of the page all explicitly specify the HTTP protocol, meaning that Firefox won't load JQuery or Lightbox due to Mixed Active Content Blocking.
Browser/OS: Firefox 52 ESR running on Linux.
